Practice Relating to Rule 65. Perfidy
Section E. Simulation of an intention to negotiate under the white flag of truce
Referring to Israel’s Law of War Booklet (1986), the Report on the Practice of Israel states that the Israel Defense Forces (IDF) prohibit “the resort to perfidy to kill, injure or capture an adversary. Therefore, the IDF does not feign intent to … negotiate under a white flag.”

Israel’s Manual on the Laws of War (1998) gives the following example of perfidy: “It is forbidden to use a white flag for an inappropriate purpose (posing as persons … seeking negotiations with a view to gaining a military advantage).”

Israel’s Manual on the Rules of Warfare (2006) states:
It is forbidden to make false use of the white flag (pretending to surrender or to be willing to negotiate while the true intention is to obtain a military advantage) so that soldiers from the other side will not fear allowing fighter[s] to live and grant them the status of prisoner-of-war.
